SPECIFICATION forming part of Letters Patent No. 773,750, dated November1, 1904.. Application filed January 6, 1904. Serial No. 187,873. (Nomodel.)

To all whom it may concern:

Be it known that I, ELMER G. KAY, a citizen of the United States, and aresident of Everett, in the county of Snohomishand State of ashington,have invented certain new and useful Improvements in Eyeglasses, ofwhich the following is a specification.

My invention relates to improvements in eyeglasses or eyeglassattachments designed particularly to be used by'watch-makers, jewelers,and others who find it necessary to use a magnifying-glass in their workand who also are obliged to wear ordinary eyeglasses or spectacles byreason of defective eyesight.

The invention aims to provide a simple and inexpensive watch-makers loopconstructed to be combined with a pair of eyeglasses in a novel manner,so as to form a permanent part of the latter or a fixed part thereofduring the use of the same in connection with the loop, and so mountedand arranged relative to the parts of the eyeglasses or spectacles thatthe magnifying-glass may occupy two positions, one in register with theaxis of one of the ordinary lenses of the eyeglasses and in advance ofthe same and another entirely out of register with said lens and out ofthe line of vision.

To this end the invention includes the combin ation and arrangement ofcomponent parts and the details of construction to be hereinafterdescribed, and particularly pointed out in the claims.

The preferred embodiments of my invention are illustrated in theaccompanying drawings, in which Figure 1 shows in perspective the sameembodied in a pair of spectacles. Fig. 2 is a plan View of theconstruction shown in Fig. 1. Fig. 3 is a cross-sectional view of thesame. Fig. 4: is a front elevation of a modification. Fig. 5 is a sideelevation of the same, parts being shown in section; and Fig. 6 is aperspective view showing another embodiment of the invention. Fig. 7 isa detail plan View. Fig. 8 is a perspective view of a modification.

In the exemplification of my invention disclosed in Figs. 1, 2, and 3the same is embodied in that form of eyeglasses usually termedspectacles and includes generally a pair of lenses carried bya frame, apost secured at its inner end contiguous to the inner edge of one lensandyprojecting in ad- Vance thereof substantially at right angles to theface of the same, and a magnifying-glass mounted upon the outer end ofthe post and designed to occupy either a position in register with theaxis of said lens or a second position entirely to one side of the lens.

In the drawings the lenses are designated by the letters a 6 and theframe by the letter 0.- The post (designated by the letter (Z) isrigidly attached at its inner end to the frame 0, contiguous to theinner edge of the lens a, and extendsoutwardly substantially at rightangles to the face of the latter. The magnifying-glass e is movablymounted upon the outer end of the post (Z, so that it may occupy twopositions relative to the lens a, one in register with the axis of thelatter and another entirely to one side of the same. The mounting of theglass 6 is so constructed that when the latter is in register with thelens a the face thereof will be in a plane substantially parallel withthe face of the lens. The particular form of mounting disclosed hereincomprises an arm f, carrying a lens-frame g at one end and a sleeve itat its opposite end, through the bore of which the post (Z extends toprovide a pivotal connection between said post and the magnifying-glassa. Means are provided to limit the pivotal movement of the arm f inorder to arrest the lens in either of the two positions which it isintended to occupy and also to hold the same a fixed distanee in advanceof the lens a. In the exemplification of my invention disclosed hereincoacting stops or shoulders on the post (Z and sleeve it are provided toperform said function. At the end of the post (Z a shoulder z' isprovided, which eoaets with the outer end of the sleeve it to preventthe axial movement of the latter in an outward direction, and othershoulders, it is, extending from the post (Z coact with the opposite endof the sleeve to prevent the inward movement of the same. The shoulderc' is preferably displaceable to permit the sleeve it to be placed onthe post (Z, and the head of a screw fitted in the outer end of saidpost may be employed to constitute said shoulder. The shoulders Z5 71;in addition to preventingaxial movement of the sleeve 7L act also tolimit the turning movement of the same by coacting with shoulders m or.upon the inner end of the latter. The shoulders m a are preferablyformed by opposite sides of a lug extending inwardly from the inner endof the sleeve 72/. hen the shoulders m 76 are in contact, the glass 0will rest in a position with its axis substantially in register with theaxis of the lens a, while when the shoulders a 7r are in contact theglass will occupy a position between the two lenses a 7) and asuflicientdistance in advance ofthe same as to be entirely out of the way. Theinner end of the post (Z is preferably secured to the frame 0 bysoldering the same thereto, although any other means may be provided forrigidly securing said end to the frame.

In Figs. 4 and 5 the invention is shown as embodied in a pair of rimlesseyeglasses or glasses of the pince-nez type. In this form of myinvention the construction of magnifyingglass 0 and the mounting of thesame upon the post (Z may be identical with that disclosed in Figs. 1,2, and 3; but instead of soldering the inner end of the post to theeyeglass-frame this end (1 is threaded to engage the threads in the ears0 0, whereby the post is rigidly supported, and in addition saidthreaded end (1 serves as the ordinary pin which is utilized to hold thelens between said cars.

In the exemplilication of my invention disclosed in Fig. 6 the same isshown as an attachment complete in itself, designed to be readilyaffixed to and detached from one of the lenses of a pair of eyeglasses.In this form of my invention the construction differs from thatpreviously described only in the arrangement of the inner end of thepost and the parts associated directly therewith. As shown in Fig. 6,the end of the post carries a spring attaching-loop r. This loop ispreferably of semielliptical or U shape and is provided intermediate ofits ends and at its ends with angularly-extending clips. The post isrigid with the intermediate portion of the loop, and the latter isdisposed in a plane parallel with the face of the magnifying-glass. Theattachment is secured to a pair of glasses by merely engaging the loopwith the edge of one lens of the same, the clips s embracing oppositefaces of said lenses.

The construction and operation of my invention will be readilyunderstood upon reference to the foregoing description and accompanyingdrawings, and it will be appreciated that the parts and combinationsrecited may be varied within a wide range without departing from thespirit and scope thereof.

.l-laving thus described my invention, what is claimed as new, anddesired to be secured by Letters Patent, is

1. The combination with a pair of eyeglasses, of a post rigidlysupported at its inner end adjacent the bridge-piece of the eyeglassesand extending in advance of the lenses, a second lens, and a framecarrying the same pivotally mounted on the outer end of the post, saidpost and second lens-frame having coacting stop-surfaces arranged toarrest the second lens in the line of vision or in a second position outof the line of vision and in the plane of the bridge-piece,substantially as described.

2. The combination with a pair of eyeglasses, of a post rigidlysupported at its inner end and extending in advance of the lenses, asecond lens, a frame carrying the same including a sleeve swivelcd onthe outer end of said post, said post having stop-surfaces extendingradially from the same, and said sleeve having longitudinally-extendingstopsurfaces coacting therewith, substantially as described.

3. The combination with a pair of eyeglasses, of a post rigidlysupported at its inner end and extending in advance of the lenses, asecond lens, a frame carrying the same, including a sleeve swivelcd onthe outer end of said post, a shoulder coacting with one end of thesleeve to limit the longitudinal movement thereof in one direction, andradial projections on the sleeve for limiting the longitudinal movementthereof in an opposite direction, the latter projections also serving tolimitthe turning movement of the sleeve, substantially as described.

4. In combination, a spring-frame having parts for embracing the edge ofa lens, a post rigidly secured to said frame intermediate of the endsthereof, and a magnifying-glass secured to the outer end of the post,substantially as described.

5. In combination, a spring-frame having parts for embracing the edge ofa lens, a post rigidly secured to said frame intermediate of the endsthereof, and a magnifying-glass pivotally secured to the outer end ofthe post, substantially as described.

6. The combination with the lens of an eyeglass, of a post rigidlysecured at its inner end contiguous to one edge of said lens, amagnifying-glass, a mounting therefor including a sleeve swivelcd uponthe outer end of the post, and coacting shoulders on the post and sleeveto limit the movement of said magnifying-glass, substantially asdescribed.

In testimony whereof I have hereunto signed my name, in the presence oftwo attesting witnesses, at Everett, in the county of Snohomish andState of Washington.
